Vary according to the photosensitising agent involved and the type of reaction it causes in the skin. The reaction can be phototoxic and/or photoallergic. Phototoxic reactions result from direct damage to tissue caused by light activation of the photosensitising agent, whilst photoallergic reactions are a cell-mediated immune response in which the agents. Although some oral photosensitising medications can cause photoallergic reactions, most cause phototoxic reactions. A handful of medications can cause both phototoxic and photoallergic reactions. The clinical features differ between phototoxic and photoallergic reactions. The main goal of treatment is to identify the photosensitising agent and if possible to avoid it. levitra alcohol interaction Photosensitivity is when an individual has an extreme sensitivity to the sun (ultraviolet rays) and other sources of light.
